' ROLLER SIDE BEARING'FOR RAILWAY-CARS.

To all whom it may concern Be it known that we, EDWIN Gr. BUSSE and ERNEST A. LE BEAU, citizens of the United States, residing at Chicago, Illinois, have invented a certain new and useful Improvement in Roller Side Bearings for Railway-Cars, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side elevational view partly in section of our improved roller side bearing for railway cars. Fig. 2 is a bottom plan view. Fig. 3 is a vertical cross secslidingly 7 arranged bearing tional view on line 33 of Fig. 2, and Fig.

1 is a vertical cross sectional view on line 44: of Fig. 2. p

This invention relates to a new and useful improvement in roller side bearings for railway cars of the single roller type having centering means, preferably in the form of springs, whose energies are normally exerted to center said roller.

While we have shown an inverted bearing designed especially to be attached to the body bolster of the car, it is obvious that this hearing could be used on the truck bolster, in which event, the roller would be presented upwardly and dirt exits provided at each end of the main casting preferably in line with the surface of the track plate.

In the drawings 1 indicates a casting having attaching lugs or ears 2 extending from its base portion. The track plate 8, preferably of hardened 'steel,isse'cured to the inner side of the base portion. The side walls of the casting are formed with inwardly presented grooves 4: in which are blocks 5 and having spring housings 6 extending upwardly from their ends in which are seated springs 7, said springs cooperating with teats 8 arranged in the housings formed in the end walls of the main casting.

9 is an axle whose endsare mounted in the bearing blocks 5 and 10 is the roller mounted on the axle between the bearing blocks and cooperating with the track plate 3. The periphery of this roller' extends beyond the plane of the edges of the hearing blocks.

vided with a recess 11 in such shape as to permit the insertion and removal of the axle in assembling and dismantling the bearing. 7

It will be observed that each of the bearing blocks is provided with contiguous lugs or ears 5* through which are passed securing rivets or bolts 5 which hold the bearing blocks in their operative position. The upper inner face of each bearing block is cut away or inclined as shown in Fig. 4 so that when the fasteningdevices 5 are removed, the bearing blocks can be tilted, as shown in dotted lines, and in that way removed from the housing. However, if it is desired not to renew the bearing blocks, but only to renew the roller, the roller carriage formed by the bearing blocks can be slightly displaced, to one side, so as to aline the axle to the recess 11.

A cotter pin 12 holds the axle in position and when the axle is alined with the recess 11 an instrument may be inserted through the opening 13 in the wall of one of the bearing blocks so as to force the axle out of the recess 11 whereby the roller may be removed. Of course the reverse operation would occur in mantling the device.

As shown, the bearing apertures for the axle 9 may be somewhat elongated vertically to permit of a slight vertical movement of the roller independently of the carriage, as well as a free spinning movement of the roller.

Although in the form shown, but one roller is employed, ity is obvious that the carriagemay be constructed so as to carry two or more rollers arranged to track one another. 7

.ment between said walls, and longitudinally of the casing, a removable axle having bearmg at its ends in said carriage, a roller mounted on said axle, the carriage being provided in one wall with an opening through which the axle is moved longitudinally to, and from position and the adjacent wall of the casing having a recess disposed within the plane of the line of movement of the carriage and to register with said open: mg, the openmg and recess belngin nonallnement when the carriage 1s in normally centered position, and springs for centering v u said carriage.

2. A side bearing for railway carscomprising a houslng and a two-part carnage mounted toslidein said housing, said carriage comprising two substantially dupli I 'cate parts whose inner bearing faces are cut away to permit the parts of the carriage to be collapsed for purposes of insertion and V removal, and means for securing the: parts prising a housing having longitudinal guide ways, a two part carriage mounted to slide in said housing and provided with flanges to seat within the guide ways, said carriage comprising two substantially duplicateparts whose inner bearing faces are oppositely'cut away at an angle to permit the parts of the carriage to be collapsed for engaging or disengaging the flanges with'the guideways,

and means for securing the parts of the car? t a riage together in their operative position. 1n 'testnnony whereof we hereunto aflix our signatures in thepresenoe of two witnesses, this12th day of May, 1914'. v
